The study focuses on the fourth resonant mode, characterized by four current segments with alternating directions, resulting in undesired multilobe radiation patterns. To address this, selective compression of the four segments is introduced to achieve high-gain omnidirectional radiation. A total of 16 compression configurations are analyzed, corresponding to all combinations of compressed and uncompressed segments. An analytical model is developed to quantify the far-field radiation as a function of segment-wise compression coefficients. Based on this analysis, two optimized designs are fabricated, exhibiting gains of 4.76 dBi and 5.11 dBi at 5.8 GHz, with fractional bandwidths of 25% and 14%, respectively. These results validate that compression-based control of even-order HOMs supports compact, high-performance omnidirectional antennas while offering enhanced design flexibility compared to HOM dipole antennas constrained to odd-mode excitation in center-fed configurations.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"25 9","pages":"3651-3655"},"PeriodicalIF":4.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148903249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, several bottlenecks are encountered by existing graphics processing unit (GPU)-accelerated SBR solvers, including the dielectric materials, numerical divergence at grazing incidence as ray density increases, and substantial computational waste. To overcome these bottlenecks, the OptiX-native dyadic modified equivalent current approximation bitmap-masked ray culling (OptiMECA-BRC) algorithm is proposed. Within this algorithm, the dielectric material problem is specifically addressed through the development of an OptiX-native dyadic modified equivalent current approximation (OptiMECA) method. Moreover, numerical divergence at grazing incidence is resolved through the implementation of a near-grazing correction. In addition, to alleviate computational resource waste in multitarget swept-angle RCS simulations, an adaptive bitmap-masked ray culling (BRC) scheme is introduced. Finally, the overall computational efficiency is further enhanced by a customized complex-valued hierarchical warp-synchronous parallel reduction scheme for fully on-device far-field accumulation. Numerical validations demonstrate that OptiMECA-BRC reduces GPU memory by up to 66.7% over conventional methods and concurrently delivers up to a 37× speedup compared to Altair field computations involving bodies of arbitrary shape (FEKO) ray launching geometrical optics (RL-GO) while maintaining close agreement.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"25 9","pages":"3831-3835"},"PeriodicalIF":4.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148902752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An embedded open-loop resonator and a finite 3 × 3 metasurface loading layer are introduced inside the cavity to form a localized loaded mode and modify its coupling to the two crossed-slot radiation channels. By combining the conventional mode excitation mechanism with the open-loop resonator excitation mechanism, the proposed structure successfully expands the single AR minimum into dual AR minimum, thereby broadening the AR bandwidth. Meanwhile, the design still retains the advantages of a low profile and a quasi-packaged structure. A prototype antenna is fabricated and measured.

The proposed antenna employs a slot-coupled stacked patch radiator combined with a 3 dB directional coupler to synthesize CP from two orthogonal linearly polarization (LP) modes. By integrating the coupler directly into the antenna feed layer, passive dual-port right-hand CP/left-hand CP (RHCP/LHCP) selection is achieved within a single element by exciting the corresponding input port. The stacked patch configuration introduces dual resonances, broadening the impedance and axial ratio (AR) bandwidth. The simulated results show the 3 dB AR bandwidth is 16.9% (26.6 GHz to 31.5 GHz) with reflection coefficients below −11.3 dB.
